Silicate mineral#Cyslosilicates

A silicate mineral is generally an inorganic compound consisting of subunits with the formula [SiO_2+n]²ⁿ⁻. Although depicted as such, the description of silicates as anions is a simplification. Balancing the charges of the silicate anions are metal cations, M^x+. Typical cations are Mg²⁺, Fe²⁺, and Na⁺. The Si-O-M linkage between the silicates and the metals are strong, polar-covalent bonds. Silicate anions ([SiO_2+n]²ⁿ⁻) are invariably colorless, or when crushed to a fine powder, white. The colors of silicate minerals arise from the metal component, commonly iron.

In most silicate minerals, silicon is tetrahedral, being surrounded by four oxides. The coordination number of the oxides is variable except when it bridges two silicon centers, in which case the oxide has a coordination number of two.

Some silicon centers may be replaced by atoms of other elements, still bound to the four corner oxygen corners. If the substituted atom is not normally tetravalent, it usually contributes extra charge to the anion, which then requires extra cations. For example, in the mineral orthoclase {{chem|[KAlSi|3|O|8|]|n}}, the anion is a tridimensional network of tetrahedra in which all oxygen corners are shared. If all tetrahedra had silicon centers, the anion would be just neutral silica {{chem|[SiO|2|]|n}}. Replacement of one in every four silicon atoms by an aluminum atom results in the anion {{chem|[AlSi|3|O|8|−|]|n}}, whose charge is neutralized by the potassium cations {{chem|K|+}}.

In mineralogy, silicate minerals are classified into seven major groups according to the structure of their silicate anion:Deer, W.A.; Howie, R.A., & Zussman, J. (1992). An introduction to the rock forming minerals (2nd edition ed.). London: Longman {{ISBN|0-582-30094-0}}Hurlbut, Cornelius S.; Klein, Cornelis ||1985). Manual of Mineralogy, Wiley, (20th edition ed.). {{ISBN|0-471-80580-7}}

Tectosilicates can only have additional cations if some of the silicon is replaced by an atom of lower valence such as aluminum. Al for Si substitution is common.
